Foam on plants

Table Of Contents:

Have you ever noticed foam on the leaves, stalks and stalks of flowers or bushes? You've probably seen foam like this before and wondered what it could be.

When you're out in the wild, you might assume the saliva comes from animals like a fox or a dog, but that's unlikely in your own backyard.

Foamhopper (Aphrophoridae)

If you find the foam close to the water, it is also possible that it could be toad foam. But neither the one nor the other is the case. However, this foam still comes from an animal, albeit from an insect. Namely from the foam cicada.

You can find the cicada when you remove the cuckoo's saliva, as the foam is also called. Underneath this insect hides, which sucks on the greens and thanks to the foam is protected from enemies and also from dehydration. So the foam is nothing more than the protective cocoon of the cicada larva. If the foam bothers you, remove it with a jet of water.

The cicada itself does little damage by the way. So it's usually quite harmless.
